Now You're Just Somebody That I Used to You (Now You're Just Somebody That I Used to Know)

This week's song, Gotye (feat. Kimbra) with "Somebody that I used to Yo." A song about navigating digital-age relationships, which are often mediated through apps and other platforms that dictate the terms and channels of communication.
The protagonist has been cut out from Kimbra's life because he has not kept up the pace of adoption — partly because he finds the level of information these apps require as being too invasive.)
